Abstract
Abstract A modular, branch circuit electrical power distribution system and components therefore, of the flexible wiring type. Lighting fixtures and devices are wired to connectors which employ contact assemblies comprising an integral combination of a male contact, a female contact, interconnecting bussbar and wire-securing means. This entire integral assembly is formed from a single piece of suitably cut and bent sheet metal stock. The integral male contact, female contact, bussbar, and wire-securing means contact assembly. This contact assembly permits power to be received from one cable set, transmitted to another cable set and tapped off to feed a fixture, receptacle, or other device. Cable sets have male connectors at one end and female connectors at the other end; other system components employ similarly corresponding sets of male and female contacts. Switches and receptacles are connected to couplers which may be fed by cable sets. The couplers are affixed to cable whips which feed wiring directly from the couplers to switches and receptacles.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A receptacle connector assembly for use in adapting an appliance to use in a flexible wiring-type branch circuit electrical power distribution system comprising: a male receptacle connector; a female receptacle connector; the male and female receptacle connectors each including a plurality of male and female electrical contacts, respectively, and housings for such contacts; the housings for male contacts being of a female type and the housings for female contacts being of a male type; each such receptacle connector including physical keying means for defining a single permissble orientation for such receptacle connector to mate to plug connector; each male contact being associated with a corresponding female contact and each such associated male-female contact pair being integrally formed from a single piece of suitably cut and bent sheet metal stock, and a portion of such sheet metal stock forming a bussbar conductor between the male and female contacts; each male contact/female contact/bussbar assembly including means for securing thereto a wire from the appliance.
Claim 2
Dependent Claim
162 words
A receptacle connector assembly for use in adapting an appliance to use in a flexible wiring-type branch circuit electrical power distribution system comprising: a male receptacle connector; a female receptacle connector; the male and female receptacle connectors each including a plurality of male and female electrical contacts, respectively, and housings for such contacts; the housings for male contacts being of a female type and the housings for female contacts being of a male type; each such receptacle connector including physical keying means for defining a single permissble orientation for such receptacle connector to mate to plug connector; each male contact being associated with a corresponding female contact and each such associated male-female contact pair being integrally formed from a single piece of suitably cut and bent sheet metal stock, and a portion of such sheet metal stock forming a bussbar conductor between the male and female contacts; each male contact/female contact/bussbar assembly including means for securing thereto a wire from the appliance.
Claim 3
Dependent Claim
39 words
The connector assembly of claim 1 wherein each male contact/female contact/bussbar assembly is formed in a generally U-shaped configuration, with the male and female contacts forming the sides of the U and the bussbar forming the bridge between them.
Claim 4
Dependent Claim
29 words
The connector assembly of claim 1 or claim 2 wherein the housings for the male and female contacts are integrally formed of molded plastic adapted to receive the contacts.
Claim 5
Dependent Claim
44 words
The connector assembly of claim 3 wherein the male contacts are arranged substantially colinearly with each other and the female contacts are arranged substantially colinearly with each other, such that the male and female connector assemblies are disposed substantially parallel to each other, side-by-side.
Claim 6
Dependent Claim
13 words
The connector assembly of claim 4 wherein the male type housings are dead-fronted.
Claim 7
Dependent Claim
66 words
The connector assembly of claim 5 wherein at least one male type housing for a female contact includes physical keying means associated with a predetermined rating electrical usuage for the connector, for preventing a male contact in a plug connector from mating therewith unless the plug connector is adapted to mate to said physical keying means, whereby only connectors having like physical keying may be mated.
Claim 8
Dependent Claim
44 words
The receptacle connector assembly of claim 6 wherein at least one of the male and female receptacles includes a contact housing having no electrical contact disposed therein and wherein such contactless housing is provided with the physical keying means associated with connector contact rating.
